Description

The present invention relates to a crockery basket of a dishwasher for receiving crockery pieces with a bottom and with the bottom framing side parts, wherein at least one row of barbs for holding the crockery pieces is arranged at the bottom, which consists of at least one barbed wire and at least one row of barbs attached thereto from individual Barbed wires consists, wherein the base wire in the area of the row of spikes is spaced from the ground and a dishwasher with a corresponding dish rack.

From the DE 72 35 591 U a crockery basket is known, which has a bottom, which is framed by side panels. Bottom and side panels consist of individual wires connected together. For receiving pieces of crockery parallel extending corrugated wires are provided at the bottom of the dish rack, are arranged on which barbed wires, each having one end. The other end of each barbed wire protrudes freely into the basket interior. The corrugated wires are used together with the barbed wires to accommodate pieces of crockery. A disadvantage of this embodiment of a dish rack is the complex production of the dish rack due to the corrugated wires. The corrugated wires, which are located in the bottom area, have the further disadvantage that crockery pieces picked up between the corrugated wires and the barbed wires, in particular small plates, protrude into a region below the crockery basket. As a result, damage to the pieces of crockery can not be ruled out by a spray arm which is often arranged below the crockery basket.

From the DE 299 21 601 U1 a dish rack for dishwashers is known in which a row of spikes for holding the pieces of crockery is arranged at the bottom. The spine row consists of a spiked base wire and a row of spiked single barbed wires attached to it. The spiky base wire lies on the bottom of the dish rack, which is a wire mesh on. The pieces of crockery are held by two rows of barbs between each two barbed wires. If the tableware, for example, small plates, so they protrude through the base mat of the crockery basket and can by a movement of a Low spray, which is located below the mesh basket in the dishwasher, damaged. In addition, the piece of tableware may come into contact with wires of the base mat of the bottom of the dish rack, whereby the piece of tableware is only kept unstable and can also be damaged.

Finally, the reveals JP 11 206691 A a crockery basket, wherein the ends of a barbed base wire are folded and fixed to the bottom of the crockery basket, wherein the base wire is spaced from the ground in the region of the row of barbs.

The object of the present invention is to avoid the disadvantages described above and to ensure a stable position of a piece of crockery in the crockery basket, thereby avoiding damage to the piece of crockery and to improve the flushing performance and drying.

The object is achieved by a crockery basket and a dishwasher with the features of the independent claims.

According to the invention, a crockery basket of a dishwasher for holding crockery pieces has a base and side parts which frame the floor. At least one row of spikes for holding the pieces of tableware is arranged at the bottom. The spine row consists of at least one spiked base wire and at least one spiked row of individual barbed wires attached thereto. The ends of the spine base wire are folded, that is bent and fixed to the ground. The attachment creates a firm and steady fixation of the row of spikes in the dish rack. The crockery basket itself is thereby reinforced and stabilized. The base wire is spaced from the ground in the area of the row of spikes.

With the present invention, a distance of a piece of crockery from the bottom of a crockery basket is effected without additional wires or additional parts in a simple and cost-effective manner. The pieces of crockery are not held in the plane of the floor, but in an overlying plane, leaving downwardly projecting parts of the crockery within the crockery basket. As a result, both a stable storage of the dishes and thus protection prevents damage and prevents the dishes outside the crockery basket from being damaged by moving parts inside the dishwasher. In addition, it is avoided that the utensils pieces during removal and insertion of the dish rack in or out of the dishwasher abut housing parts of the dishwasher and thereby could be damaged.

In the crockery basket constructed according to the invention, the holder of the crockery pieces in the rows of barbs is achieved without significant additional expense in the manufacture of the crockery basket. By bending or bending over the ends of the spiked base wire and by attaching these bent ends of the spiked base wire to the ground, in particular the central area of the spiked base wire, to which the individual barbed wires are attached, is lifted off the ground. In particular, between the middle region of the spiked base wire and the ground thus creates a distance of the spiked base wire from the ground. If the pieces of tableware are placed and held at least partially on the spiked base wire, these pieces of tableware, in particular small plates, protrude into the area between the spike base wire and the ground, but not below the floor. They are thus protected against damage from below. Usually, the pieces of tableware are conveniently held by two similar trained rows of spikes, each piece of tableware are arranged on two parallel spine base wires and between a total of four barbed wires. The piece of crockery is thus held above the ground.

Advantageously, the floor consists of a base mat of wire. This base mat, which essentially corresponds to a wire mesh, is inexpensive to produce and ensures good accessibility to the piece of tableware for the cleaning fluid and a good drying of the piece of crockery. The base mat made of wire allows a good stability of the crockery basket with the least possible coverage of the piece of crockery compared to the cleaning liquid and the best possible dripping of the drying piece of crockery.

If the base wire is fastened with its ends to the base mat, a particularly simple connection between the base mat of the floor and the spine base wire becomes possible scored the spine row. The attachment of the base wire with the base mat is advantageously carried out by welding. The spiked row is thus arranged firmly in the dish rack and thus enables a very stable mounting of the pieces of tableware.

If the base wire is fastened, in particular welded, to wires of the base mat which run transversely to the base wire, then a very simply designed connection is created which is easily weldable. The connection is durable, without the need for additional fasteners.

According to the invention, in addition, one end of the base wire has a double edge, in which preferably both edgings are substantially perpendicular to one another and the wire piece after the second edging runs essentially parallel to the wire piece before the first edging. The edging preferably takes place essentially in the plane of the spiked row. As a result, the length of wire of the spiked base wire running between the first and second edgings essentially determines the extent of the distance of the spiked row or of the spiked base wire from the ground. The wire end after the second edging allows a very simple connection to the ground, in particular a base mat of the soil by this wire end is placed on the wire of the soil and connected to this, in particular welded, is.

Moreover, according to the invention, since one end of the base wire has a single edge, a connection to the bottom, in particular a base mat made of wire, is expediently very simple by crossing the two wires together. This simply folded end of the base wire is crossed with the wire of the base mat, whereby a connection of these two crossed wires, for example by welding, is possible. Spacing of the spine row is accomplished by connecting the free end of the spiked base wire to the ground and thereby extending the portion of the spiked base wire to which the spine row of individual barbed wires is secured spaced from the bottom of the dish rack.

According to the invention, it is provided that one end of the base wire has a single edge and the other end has a double edge. While the end with the Single bend is attached to a wire of the base mat of the floor, the end of the base wire with the Doppelkantung lies on or under another wire of the base mat and is also connected to this. The advantageous double edge creates a contact area of the spiked base wire on the wire of the base mat, which allows the attachment of the spiked base wire to the wire of the base mat on a longer area, namely over the entire length of the free end of the spiked base wire. This makes it possible to compensate for the manufacturing tolerances of the base mat of the dish rack and the row of spikes with the spiked base wire. By increasing the permissible manufacturing tolerances, in turn, a measure is taken to enable a cost-effective production of the crockery basket according to the invention.

Advantageously, the attachment of the spiked base wire to the base mat of the dish rack takes place in that the simply folded end of the base wire takes place as a direct side weld on a wire of the base mat and the other, twice folded end of the base wire for tolerance compensation on the top or bottom of another wire the base mat is welded. The simply canted end of the base wire causes thereby also a longitudinal stop of the base wire and thus the spiked row, while the double-folded end of the base wire causes a secure bearing of the base wire in the vertical direction. In particular, by the single folded end of the base wire parallel alignment of mutually associated barbed wires of two parallel rows of spikes is made possible without special facilities or provisions must be provided. As a result, in turn, a very simple, fast and cost-effective production of the dish rack according to the invention is possible.

The distance of the base wire from the bottom of the dish rack is determined in particular by the length of the bent ends of the base wire. They lead by attachment to the bottom of the dish rack to a distance of the support points for the piece of crockery. The piece of crockery is picked up between two rows of spikes and is located between a total of four barbed wires and rests on the two base wires of the rows of spikes. Due to the distance of the spiked base wire from the bottom of the dish rack is advantageously causes a piece of crockery received therein, in particular a Plate, the bottom of the dish rack or the base mat does not touch or even protrudes through it. The piece of crockery is thereby stably absorbed and also protected from damage.

Preferably, the barbed wires are obliquely aligned with respect to the base wire. As a result, the inclusion of voluminous pieces of crockery is facilitated and improved by an inclination of the crockery both the cleaning and the drying of the crockery. The skewing of the pieces of crockery creates no or only a few places on the piece of crockery, which run horizontally, so that the water can drain off quickly and without leaving any traces of dry.

A dishwasher with a crockery basket described above is inexpensive to produce and provides a very good cleaning and drying results of the crockery contained therein.

When inventively designed crockery basket is avoided by establishing a distance of a piece of crockery from the base mat of a crockery basket that arise on the crockery undefined contact points, whereby the flushing performance and drying is improved. While in comparable dishwashers a distance is made by means of additional wires or additional parts, which increase their cost by introducing them into the cutlery basket, the present invention provides a cost-effective and reliable dish rack. The crockery basket construction according to the invention describes a fixed row of stacks of a crockery basket, with which it is possible, without the use of additional wires, to lift crockery pieces from a base mat and to prevent contact points. The distance is preferably realized by targeted edges of the spiked base wire at the beginning and end. The spiked row in a preferred embodiment has two different bends at the ends. In particular, a single bend serves as a direct weld point, preferably a double bend serves as a tolerance compensation of the second weld in order to compensate for the manufacturing tolerances. Advantages of the inventively constructed dish rack are the simplified production, which is integrated into the sting production and requires only a small additional effort for edging or bending of the wire ends. No additional bent or canted wire is necessary whereby a time and cost savings compared to known solutions is achieved.

Other developments of the invention are given in the dependent claims. The invention and its further development as well as its further advantages are described in the following exemplary embodiments. Each show schematically:

FIG. 1

a section through a crockery basket,

FIG. 2

a section through two parallel rows of spikes, and

FIG. 3

a perspective view of a section of a dish rack.

FIG. 1 is a schematically illustrated section through an inventively constructed crockery basket 1. The crockery basket 1 consists of a base mat 2, which forms the bottom of the mesh basket 1. The floor is framed by side panels 3.1, 3.2 and 3.3. A fourth side part is not shown. The side parts 3.1, 3.2 and 3.3 are made as well as the base mat 2 of the floor of cross-connected wires. These wires cause little shielding of the dishes to be cleaned and thus a very good drying of the dishes, since no backwater forms. A piece of tableware 4 is shown schematically in the dish rack 1.

The base mat 2 consists of longitudinal wires 2.1 and cross wires 2.2a to 2.2d. For receiving pieces of crockery 4 a spiked row 5 is provided. The spine row 5 consists of a plurality of barbed wires 5.1, which are attached to a spine base wire 5.2. The barbed wire 5.1 is fixed at right angles to the spiked base wire 5.2 in the present embodiment, in particular welded, and angled in the further course to this. The angling causes the piece of crockery 4 to be held at an angle, so that no backwash water forms on the crockery piece 4 and thus no drying stains are formed. Preferably, all essential surfaces of the held piece of tableware 4 are inclined at an angle of about 30 ° to the horizontal, so that the water can flow well from the piece of tableware 4. The piece of tableware 4 is held between two barbed wires 5.1 a spiked row 5. It continues to rely on the barb base wire 5.2.

In particular, the spiked base wire 5.2 is canted at its ends. The folded ends are in turn attached to the ground. In the present embodiment, the barbed base wire 5.2 has a double fold at its left end. The resulting central piece 5.2a is angled substantially at right angles to the spine base wire 5.2. The outwardly projecting end piece 5.2b after the second fold essentially runs parallel again to the spiked base wire 5.2. The end piece 5.2b is attached to the transverse wire 2.2a of the base mat 2 of the floor, in particular welded. At the other end of the spiked base wire 5.2 is in the present embodiment, a further end piece 5.2c, which is bent relative to the spine base wire 5.2 only simple and substantially at right angles thereto. Also, this end piece 5.2c is connected to the bottom, here with the transverse wire 2.2d of the base mat 2, in particular welded.

Due to the different bends of the end pieces 5.2b and 5.2c causes the barbed base wire 5.2 is struck against the transverse wire acting as a stop 2.2d and fixed there. The position of the spiked base wire 5.2 is thereby defined quite accurately. At the other end of the spiked base wire 5.2 an attachment point is created by the double fold and thereby parallel to the barb base wire 5.2 extending end piece 5.2b, which rests on the transverse wire 2.2a of the base mat 2 of the floor and fixed there, in particular welded. As a result, a tolerance compensation is possible, which results from manufacturing tolerances of the bottom or the base mat 2 and the spiked row 5. By this design several millimeters can be compensated, which are not essential for the function of the row of spikes 5, however, makes the manufacture of the dish rack 1 and the row of spikes 5 much easier and cheaper to do.

The lengths of the middle piece 5.2a and the end piece 5.2c are coordinated so that the end piece 5.2c laterally abuts the transverse wire 2.2d and can be fastened there, while the end piece 5.2b at the other end of the spiked base wire 5.2 on the approximately the same Height of transverse wire 2.2a rests. As a result, a parallel alignment of the spiked base wire 5.2 is effected to the bottom or the base mat 2. In particular, by a predetermined length of the middle piece 5.2a and the end piece 5.2c is also causes a distance A between the spiked base wire 5.2 and the base mat 2 is formed. This distance A is to be chosen in particular such that pieces of tableware 4 which are intended to be received in the spiked row 5 do not come into contact with the base mat 2 or the floor and also do not protrude through the base mat 2 or the floor. This ensures that, for example, spray arms, which move below the base mat 2, do not come into contact with the piece of tableware 4 and thus could lead to damage of the piece of tableware 4. In addition, a stable reception of the piece of crockery 4 is effected by the use of two parallel rows of spikes 5, as will be explained in more detail in the following figures.

In FIG. 2 is accordingly a view across the representation of FIG. 1 shown in a section. It is the piece of tableware 4, here a plate shown, which is superimposed on two parallel spine base wires 5.2. The piece of tableware 4 is still supported on the barbed wires 5.1 of the two rows of spikes 5. The spine base wires 5.2 are at a distance A from the cross wire 2.2b to prevent the piece of tableware 4 from coming in contact with the cross wire 2.2b. The distance A can, depending on the design and arrangement of the row of spines 5 with respect to the transverse wires 2.2a to 2.2d or the longitudinal wires 2.1 as a distance between the spiky base wire 5.2 and the longitudinal wire 2.1 or as a distance between the spiked base wire 5.2 and the cross wire 2.2a to 2.2d be determined. It is essential in any case that no contact between the intended piece of crockery 4 and one of the longitudinal wires and transverse wires 2.1, 2.2 takes place.

FIG. 3 shows a schematic perspective view of a section of an advantageous crockery basket 1, which is constructed according to the principle of the invention. Again, the two substantially parallel rows of spikes 5 are shown. Each spine row 5 has a spiked base wire 5.2 to which a plurality of barbed wires 5.1 are attached. The ends of the spiked base wire 5.2 are provided on one side with a single edge and on the other side with a double edge. As a result, a stop in the horizontal direction and on the other side is on the side of the single edge by means of the double edge creates a vertical stop the spiked row 5. Manufacturing tolerances are compensated by these two different stops. The spiked row 5 can be fixedly arranged on the ground, here on the base mat 2. Between two sting rows 5 the piece of crockery 4 is held by the barbed wires 5.1 and the barbed base wires 5.2. Contact with the bottom of the crockery basket 1 is avoided by the distance of the barbed base wires 5.2 from the bottom of the crockery basket 1 when using the provided crockery pieces 4.

The present invention is not limited to the illustrated embodiments. In particular, similar bends are possible at the ends of the spine base wires. The spine base wires 5.2 can also be attached to the longitudinal wires 2.1 of the base mat 2, if this is advantageous in the dish rack 1 and its division. It is particularly advantageous that no additional bent or canted wire is required, but that the distance of the spiked base wire 5.2 is achieved solely by its shape. As a result, a simple production, which is integrated into the sting production, with only a small amount of time to edge or bending of the wire ends and thus a significant cost savings compared to known rows of spikes achieved. The holder of the pieces of tableware according to the invention is carried out at a distance from the base crockery basket, whereby a good cleaning and drying while maintaining stable support of the crockery pieces is achieved.
